tinhead, thanx for explanation. I have just spotted in another thread where the killerwhale user successfully cracked FW 2.05, see this post (link), which makes me one step closer to the deal. Now I see how many amazing people is attracted to this forum.

If anyone of you bought Rigol on dealextreme.com please PM me and share experience. They sell this unit for $340 at the moment, which is cheapest price ever found. I am from EU so I do not bother warranty, so it can come directly from Hongkong, to give middle finger to local reseller who wants >$600.

cheers,
-andy.

If you ever need to open your Rigol up: https://www.eevblog.com/forum/index.php?topic=2092.0

Thanks for clearing that up.

So it's a 1GS/s scope, as long as you treat it as a single channel scope with a short memory depth. 250MS/s brings it in the range of older generations with inadequate sample rate to prevent aliasing (unless they have a really steep roll-off of the input circuit, but most bandwidth measurements suggest that it's too shallow, and converting it to 100MHz makes it worse). If you want 1GS/s, 8kpts only lets you use the extra sample rate at the fastest sweep speeds, just like the older DSO's with short memory. So it's not actually that much better than the old generation, the only advantage is that you can choose your poison (aliasing due to inadequate sample rate or aliasing due to inadequate memory).

None of this is an issue if you don't stretch the limits of its frequency response, obviously, but why convert it to 100MHz if your signals don't come anywhere near that frequency?

The Instek GDS-1062 (IIRC 1GS/s for one channel with long memory, 500MS/s for two channels with long memory) now looks even better compared to the Rigol DS1052E.

I just wanted to share good news, I am next happy user of Rigol. After 4 weeks the delivery from china from dealextreme.com has come as plain and cheap "air mail". I got my device well packed and working fine. I got 2.05 SP1 is waiting for firmware hacking ;)
Damn the national customs, I have to pay 23% tribute but still it sumes up to 2/3 or price of local reseller.

cheers,
andy.

Hi all,

I'm new to this forum, I would like to purchase a Rigol DS1052E Oscilloscope and modify it to a 100MHz DS1102E.

I've read all the messages up to page 28 and read how a terminal program on a PC can be connected to the RS232 port. And used to change the Model and Serial number, I shouldn't have any problems with doing that.

The messages were some time back. I wonder if Rigol have now changed the firmware so that you can't modify the DS1052E into a 100MHz oscilloscope.

Does anyone know if you are still able to modify the oscilloscope, or is there a new way to do this...  ???

Thanks for your help.
